For full details:

Check out, and give Metals a try!

  • Add support for textDocument/selectionRange
  • [Scala 3] Inferred Type code action and other improvements
  • Better support of scalafmt for Scala 3 projects
  • Search symbol references from dependency source in the workspace

Add support for textDocument/selectionRange

Due to the great work by @ckipp01 Metals now implements the textDocument/selectionRange LSP-method. It allows you to easily select an expression and expand/shrink it using shortcut combinations:


Default keybindings in VSCode:


[Scala3] Inferred Type code action and other improvements

We're hard at work ensuring that the same feature-set for Scala 2 is available for Scala 3. This release adds support for the Insert Inferred Type code action.


In addition to other small fixes, it's worth mentioning that the Go to Definition functionality was improved so that in situations where there are compilation issues, you're now able to better navigate to the definition site.

Better support of scalafmt for Scala 3 projects

In order to support different Scala dialects scalafmt added a runner.dialect setting to support Scala 3. Metals will now correctly generate and even automatically upgrade your .scalafmt.conf. Moreover, in projects that contain different Scala major versions Metals will set a separate dialect for each separate source directory.

Search symbol references from dependency source in the workspace

Thanks to @Z1kkurat "Find References" now also works from within your dependency sources to include references from all workspace sources. Previously, it included only local occurrences in the dependency source file.



  • Fixed issues with Metals client still running after closing window
  • Fixed indexing of Scala 3 libraries that include macros
  • Fixed issues with breakpoints not stopped when using optional braces
  • Print type decorations for synthetic apply
  • Wrap autofilled arguments with backticks
  • Don't offer to organize imports when there is an error in the file


Big thanks to everybody who contributed to this release or reported an issue!
